-
Came up with the explanation/idea of the atom and made up the atomic theory
-
Modern scientist
-
Proposed his version of the atomic theory which was the first at the time.
-
A physicist that is credited for finding the proton, and the discoverer of anode rays.
-
Also developed a plantetary model of the atom and developed Japanese during the early Meiji period.
-
Used the cathode ray experiment to find the electron.
-
used the alpha particles to find the nuclues and that it is mostly positively charged.
-
Measured the charge of the electron.
-
One of world's most phenominal scientists. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.
-
The Kaluza-Klein theory was established in 1921 by Theodor Kaluza and Maxwell equations. In physics, Kaluza–Klein theory is a model that seeks to unify the two fundamental forces of gravitation and electromagnetism.
-
Made the Planetary Model of the atom and also developed an explanation of atomic structure that underlies regularities of the periodic table of elements
-
Discovered that the electron had a dual - nature to both particles and waves
-
Created Schrodinger equation off of wave mechanics.
-
Made foundational contributions to quantum mechanics. Also won the 1932 Nobel Peace Prize.
-
Discovered the nuetron
-
He received the Nobel Prize in Physics for his "decisive contribution through his discovery of a new law of Nature, the exclusion principle or Pauli principle," involving spin theory, underpinning the structure of matter and the whole of chemistry.
-
Gell-Mann's work in the 1950s involved recently discovered cosmic ray particles that came to be called kaons and hyperons. Classifying these particles led him to propose that a quantum number called strangeness would be conserved by the strong and the elementary interactions, but not by the weak interactions. He is still alive to this day
-
Was awarded 1966 Nobel Piece Prize by Robert Mulliken in chemistry molecular orbital theory.
-
Won the 1969 Nobel Peace Prize for the discoveries concerning the classification of elementary particles and their interactions. He is still alive to this day
